CyberGIS-Jupyter for Water Quarterly Release Announcement (2022 Q1) [full-version]

Dear CUAHSI community members,

We are pleased to announce a new release of the CyberGIS-Jupyter for Water (CJW) platform at https://go.illinois.edu/cybergis-jupyter-water. This release includes several new capabilities and features summarized as follows.

1) Integration of WRFHydro model with CyberGIS-Compute V2 to simplify access to High-Performance Computing (HPC) environments: A newly developed computation job template in CyberGIS-Compute enables users to configure a WRFHydro model and submit it to a HPC resource for execution. The client tool of the CyberGIS-Compute suite, CyberGIS-Compute SDK, walks users through job configuration, data transfer, job submission, and job status monitoring in a guided graphical interface. Since the overhead of HPC access is handled by CyberGIS-Compute, users can now focus on the modeling work. Currently, the implementation allows users to change almost every setting and configuration for a WRFHydro 5.x “offline run”. The whole process described above can be accomplished entirely within a notebook environment on CJW. Please refer to the example notebooks below for additional details.

2) Transition to JupyterLab: Starting with this release, CJW will launch the “next-generation notebook interface”, JupyterLab, as the default user environment. Although the new interface is different from the classic Notebook interface in many places, we anticipate this transition would be easy and smooth for most users. All existing notebooks should continue to run without modification, and the bug report and announcement UI elements have been migrated to the Lab interface. In addition, we have integrated the CUAHSI “HydroShare-on-Jupyter” extension - a handy tool that enables users to move data between CJW and HydroShare through a simple graphical user interface.

3) The “cjw” Command Line Interface (CLI): The “cjw” CLI is designed to help users manage different kernels on CJW for advanced use cases. For example, users can use this capability to set up personal kernels that will persist between sessions. For a quick start, open a terminal on CJW and try out the \"cjw -h\" command. Check out the documentation and examples below.

4) New Modules and Kernels: To support the latest RHESSys codebase, we have added Clang, a new C family compiler supplementing the existing GCC suite, to the CJW Easybuild-based toolbox. Accordingly, a new versioned RHESSys (2022-03) kernel has been created with Clang and other development tools pre-activated that are necessary for compilation of the RHESSys source code. Upon user requests, a new versioned WRFHydro (2022-03) kernel has been created to include the hvPlot toolset for advanced data visualization and updated versions of all the libraries from the previous WRFHydro (2021-09) kernel.

CyberGIS-Jupyter for Water季度发布公告（2022年第一季度）[完整版]

尊敬的CUAHSI社区成员：

我们很高兴地宣布，CyberGIS-Jupyter for Water（CJW）平台新版本正式发布，访问地址为https://go.illinois.edu/cybergis-jupyter-water。本次更新包含多项新功能与特性，概述如下：

1. WRFHydro模型与CyberGIS-Compute V2集成，简化高性能计算（High-Performance Computing, HPC）环境访问流程：CyberGIS-Compute新增了计算作业模板，支持用户配置WRFHydro模型并提交至HPC资源执行。CyberGIS-Compute套件的客户端工具——CyberGIS-Compute软件开发工具包（Software Development Kit, SDK），将通过引导式图形界面协助用户完成作业配置、数据传输、作业提交及状态监控。由于HPC访问的相关开销已由CyberGIS-Compute统筹处理，用户可专注于建模工作。目前该实现支持用户修改WRFHydro 5.x‘离线运行’的几乎所有设置与配置项。上述完整流程均可在CJW的笔记本环境中完成，详细信息请参阅下文的示例笔记本。

2. 迁移至JupyterLab：自本版本起，CJW将以“下一代笔记本界面”JupyterLab作为默认用户环境。尽管新界面在诸多方面与经典Notebook界面存在差异，但我们预计多数用户可轻松平滑地完成过渡。所有现有笔记本无需修改即可正常运行，且错误报告与公告UI元素已迁移至Lab界面。此外，我们还集成了CUAHSI的“HydroShare-on-Jupyter”扩展工具——该工具可通过简洁的图形用户界面实现CJW与HydroShare之间的数据互传。

3. “cjw”命令行界面（Command Line Interface, CLI）：“cjw”命令行界面旨在帮助用户在CJW上管理多种内核以满足高级使用需求。例如，用户可通过该功能设置可在会话间持久保存的个人内核。快速入门方式为：在CJW中打开终端并执行`cjw -h`命令。详细文档与示例请参阅下文。

4. 新增模块与内核：为支持最新的RHESSys代码库，我们在CJW基于EasyBuild的工具链中新增了Clang——一款补充现有GCC套件的C家族编译器。据此，我们创建了搭载Clang及其他编译RHESSys源代码所需预激活开发工具的带版本号的RHESSys（2022-03）内核。应用户需求，我们还新增了带版本号的WRFHydro（2022-03）内核，该内核集成了用于高级数据可视化的hvPlot工具集，并更新了上一版WRFHydro（2021-09）内核中的所有库文件版本。
